People demand online privacy as if it were some god-given right.
Declaration of Independence
We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.--That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed,
The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.
The enumeration in the Constitution, of certain rights, shall not be construed to deny or disparage others retained by the people.
I suppose it depends upon whether or not you believe in God, but certainly the protection of privacy has a long tradition among English speaking people.
